DELTA 1 R/B, 2661
Orbit data source: Space-Track
DELTA 1 R/B, 2661 is space debris in SSO originally from a launch on Thu, 26 Jan 1967 UTC launched from the Air Force Western Test Range (AFWTR). Debris objects in space refer to the collection of defunct objects orbiting the Earth. Examples of debris include non-operational satellites, rocket bodies, and fragments generated from explosions, collisions, or faulty payload assembly.
